It reminds me of Anthony Burgess's novel A Clockwork Orange. He realized that any real-world slang would soon become out of date so he invented his own slang language, Nadsat, for the characters to speak. Of course, this can be taken too far, where the made-up language comes to dominate the work with the story being an afterthought. Like some of JRR Tokien's works, for example. In fact you could say that TAOCP is the LOTR of computer science.

If you show a nonprogrammer a screen which has a user interface which is 100% beautiful, they will think the program is almost done.

People who aren't programmers are just looking at the screen and seeing some pixels. And if the pixels look like they make up a program which does something, they think "oh, gosh, how much harder could it be to make it actually work?"

While Brexit means London soon won't have access to the EU's open market across the continent,

Nobody knows yet whether this will turn out to be true. The negotiators may be able to cook up some deal that keeps the UK within the single market but outside the European Union (broadly as happens for Norway). On the other hand, a complete break is also a possibility.

How do you connect the two UP2715K screens to the Macbook Pro? Since each of them requires two DisplayPort 1.2 outputs to work at full resolution and refresh rate. Does the Macbook really have four DisplayPort outputs?

I used to have up to five screens (there were some Dell 4k monitors and old IBM T221s in the mix) but I got neck problems from turning my head to the side too much. So I have limited myself to screens more or less straight in front.
